Thanks for the link steve,I'm running a 273 gear and hope this will work better with timing at 106.I still would like to perform a compression check.Prior install it had 180 I'm expecting 190 -195 ,if it goes higher then 200 I'll be going back to 108.

What is your engine size and CR? The higher your CR the greater the change in cranking compression will be for a ICL change. A 10.0:1 455 should see an increase of a little under 5 psi going from 108 ICL to a 106 ICL.
